摘要: 目的与方法 由于标准 CRRT治疗装置价格昂贵,在床位少的医院使用频率不高,从效益价格 比考虑,一般医院很难承担。1995年起,我们利用普通人工肾机自行设计的床边连续性透析治疗装置(如彩图所示)代替CRRT机施行床边连续性血液净化治疗。结果 经过123例患者643次临床治疗应用,其中普通间歇性透析(IHD,203例次),血液透析滤过(HDF,107例次),血液灌流及透析灌流串联(45例次),单纯超滤(UF,28例次),静脉-静脉连续性血液透析滤过(CVVHDF,146例次)和静脉-静脉连续性血液滤过(CVVH,114例次)等治疗,取得了良好的效果,每次连续治疗4~22小时(平均7.8小时),血流量60~250毫升/分钟。透析液流量500~800毫升/分钟,透析液温度根据患者治疗的需要在35至38℃之间调节,如患者需要降温可调制35℃。每次治疗可以清除血尿素氮和肌酐高达50%~85%,治疗期间很好地维持电解质和酸碱平衡稳定,同时我们还观察了个别患者血清中的细胞因子和炎症介质(TNF,IL-6,CRF),结果证明经过8~12小时的持续性替代治疗后,这三种炎症介质可以降低43%~63%。治疗有效率100%,患者存活86%,其中成功率最高的是急性肾功能衰竭、慢性肾功能衰竭并发心功能衰竭及药物中毒患者(90%以上),死亡率最高的是多器官功能衰竭的患者,死亡的患者多与透析治疗无关。结论 该床边血液净化装置可以完全替代CRRT机,而且在透析滤过治疗时优于CRRT机。

Abstract: Objective and Metheds The standard CRRT instrument is too expensive for some small hospitals to afford for severe patients. hence From 1995, we used common dialysis machine to design a bedside blood purification device.
Results Until now we have used it to treat 123 patients with chronic or acute renal failure caused by any kinds of diseases. We performed 643 episodes of treatment, including IHD intermittent hemodialysis (203 patient times), HDF hemodiafiltration(107 patient times), HP hemoperfusion or HP plus HD hemodialysis (45 patient times), SUF single ultrafiltration (28 patient times) and CVVHDF continuous venorenous hemodiafiltration (146 patient times) and CVVH continuous venovenous hemofittration (114 patient time). Every treatment episode continued 4~22 hours (mean value 7.8hours), blood flow was about 60~250ml/dl, dialysate flow was about 500~800ml/l. In our experience, we can use this device to decrease BUN or SCr to 50~85% and it can also decrease inflammatory mediator such as TNF, IL-6 or CRF to 43~63% in one treatment episode. Conclusion This device is safe and it is easy to perform in clinical practice. And it can increase the survival rate of MOF, CRF and ARF patients in ICU just as CRRT does.
